I found the only public crossfire speed hack i did not make the hack and I don't take any credit for this hack. Note this speed hack is not as fast as the other speed hacks that were out previously.
instructions
-get a good injector i suggest Perx
-run Perx as admin with vista
-inject first the NBspeedhack.dll then the NBproductions.dll in that order
-go to crossfire properties and set crossfire in windows 2000 compatibility mode
-run crossfire and a window will pop up minimize crossfire and set speed to 1.3-1.5 and keep sleeptime at 5 if u set speed hack higher then 1.5 the hack will work but will dc from game in about 10 secs
-also i have vista so I'm not sure if it will work on XP so if u have XP play around with compatibility mode and try it not in compatibility mode and post what works in the comments.

I think this hack does other stuff like increased fire-rate, increased reload speed, reduced spread/recoil but I'm not sure about there try them out for yourself.
I will upload a youtube video soon.
And I have to thank NeverBorn for posting this hack for combat arms but I found it to work better on crossfire.
